Hi,
Besides fstat(), I have also found when call malloc() and fopen(),
there are serveral places that do not check their return value.
Though it is a small probability for the two functions to fail,
but it is better to fix them.
So i added these patches to this patch-set
v2 -> v3:
-ivshmem: change the error message which advised by Levente Kurusa
-others: add six new patches which check the return value of malloc() and
fopen(),
- which may be failed.
v1 -> v2:
-ivshmem: modified the log message according to reviewing suggestion of Michael
Li Liu (3):
tcg: check return value of fopen()
block/vvfat: fix setbuf stream parameter may be NULL
qtest: check the value returned by fopen()
zhanghailiang (7):
l2cap: fix access freed memory
monitor: fix access freed memory
virtio-blk: fix reference a pointer which might be freed
ivshmem: check the value returned by fstat()
util/path: check return value of malloc()
slirp: check return value of malloc()
linux-user: check return value of malloc()
